This command list the audio decoding capabilities for a given profile and configuration of a device. The GetGuaranteedNumberOfVideoEncoderInstances command can be used to request the minimum number of guaranteed video encoder instances (applications) per Video Source Configuration.

The correct syntax for the StreamSetup element for these media stream setups defined in 5.1.1 of the streaming specification are as follows:

1. RTP unicast over UDP: StreamType = "RTP_unicast", TransportProtocol = "UDP"
2. RTP over RTSP over HTTP over TCP: StreamType = "RTP_unicast", TransportProtocol = "HTTP"
3. RTP over RTSP over TCP: StreamType = "RTP_unicast", TransportProtocol = "RTSP"

If a multicast stream is requested the VideoEncoderConfiguration, AudioEncoderConfiguration and MetadataConfiguration element inside the corresponding media profile must be configured with valid multicast settings.
For full compatibility with other ONVIF services a device should not generate Uris longer than 128 octets. This command starts multicast streaming using a specified media profile of a device. Streaming continues until StopMulticastStreaming is called for the same Profile. The streaming shall continue after a reboot of the device until a StopMulticastStreaming request is received. The multicast address, port and TTL are configured in the VideoEncoderConfiguration, AudioEncoderConfiguration and MetadataConfiguration respectively. This command stop multicast streaming using a specified media profile of a device Synchronization points allow clients to decode and correctly use all data after the synchronization point. For example, if a video stream is configured with a large I-frame distance and a client loses a single packet, the client does not display video until the next I-frame is transmitted. In such cases, the client can request a Synchronization Point which enforces the device to add an I-Frame as soon as possible. Clients can request Synchronization Points for profiles. The device shall add synchronization points for all streams associated with this profile. Similarly, a synchronization point is used to get an update on full PTZ or event status through the metadata stream. If a video stream is associated with the profile, an I-frame shall be added to this video stream. If a PTZ metadata stream is associated to the profile, the PTZ position shall be repeated within the metadata stream. A client uses the GetSnapshotUri command to obtain a JPEG snapshot from the device. The returned URI shall remain valid indefinitely even if the profile is changed. The ValidUntilConnect, ValidUntilReboot and Timeout Parameter shall be set accordingly (ValidUntilConnect=false, ValidUntilReboot=false, timeout=PT0S). The URI can be used for acquiring a JPEG image through a HTTP GET operation. The image encoding will always be JPEG regardless of the encoding setting in the media profile. The Jpeg settings (like resolution or quality) may be taken from the profile if suitable. The provided image will be updated automatically and independent from calls to GetSnapshotUri. A device returns the information for current video source mode and settable video source modes of specified video source. A device that indicates a capability of VideoSourceModes shall support this command. SetVideoSourceMode changes the media profile structure relating to video source for the specified video source mode. A device that indicates a capability of VideoSourceModes shall support this command. The behavior after changing the mode is not defined in this specification. Get the OSDs. Get the OSD.
